Technical Field
[0001] This utility model relates to the field of mechanical engineering technology, and in particular to an adjustable angle steel cable guide bracket. Background Technology
[0002] In modern industrial production and infrastructure construction, steel cables are widely used in many fields such as port hoisting, construction, mining, and cable car transportation, undertaking key tasks such as material conveying, equipment traction, and heavy lifting. In mining scenarios, steel cables pull mine cars through tunnels, efficiently completing ore transfer. Furthermore, cable cars in scenic areas rely on steel cable systems to provide tourists with a safe and comfortable high-altitude sightseeing experience. Therefore, the stable and efficient operation of steel cables is not only directly related to the smoothness and safety of the entire operation process, but also has a profound impact on production efficiency, economic benefits, and social benefits. Once a steel cable malfunctions, it may lead to port paralysis, construction delays, mine shutdowns, or even serious safety accidents, causing incalculable losses.
[0003] However, existing adjustable-angle steel cable guide supports have the following disadvantages: (1) Traditional brackets have fixed angles, which makes it difficult to meet the guiding requirements of steel cables in scenarios such as horizontal turning and oblique traction. Frequent equipment replacement or manual adjustment is required, which is time-consuming and labor-intensive. (2) Traditional open guide structures are not good at limiting the lateral displacement of steel cables. When the steel cable is subjected to lateral force or centrifugal force, it is easy to derail due to constraint failure.
[0004] Therefore, this utility model provides an adjustable angle steel cable guide bracket. Utility Model Content

[0010] Optionally, the surface of the placement seat is fixedly connected with four limiting rods, which are distributed in a rectangular shape around the placement groove to form a rigid limiting boundary and prevent the placed steel cable from tipping over.
[0011] Optionally, a rotating groove is provided on the inner sidewall of the cavity, and one end of the worm is rotatably connected to the inside of the rotating groove.

[0012] (III) Beneficial Effects This utility model provides an adjustable angle steel cable guide bracket, which has the following beneficial effects: 1.

Detailed Implementation
[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.
[0017] Please see Figures 1 to 4 This utility model provides a technical solution: an adjustable angle steel cable guide bracket, including a bracket 1, a cavity is opened inside the bracket 1, a rotating component 2 is arranged inside the cavity, a lower clamping plate 3 is fixedly connected to the surface of the rotating component 2, an upper clamping plate 4 is rotatably connected to the surface of the lower clamping plate 3, and a guide component 5 is arranged on the surface of the lower clamping plate 3. The rotating assembly 2 includes a motor 201 fixedly connected to the inner wall of the cavity. The output end of the motor 201 is splinedly connected to a transmission rod, which connects the motor 201 and the worm gear 202, transmitting the power output by the motor 201 to the worm gear 202, thus acting as a bridge for power transmission and ensuring that the power can be transmitted stably and efficiently from the motor 201 to the worm gear 202. One end of the transmission rod is fixedly connected to the worm gear 202, and a worm wheel 203 meshes with the surface of the worm gear 202. A rotating rod 204 is fixedly inserted through the center of the worm wheel 203. The rotating rod 204 is a key component connecting the worm wheel 203 and the lower clamping plate 3, transmitting the rotational motion of the worm wheel 203 to the lower clamping plate 3, causing the lower clamping plate 3 to adjust its angle, thereby changing the angle of the entire guide bracket 1 to adapt to different running paths of the steel cable. One end of the rotating rod 204 is fixedly connected to a connecting block 205, the bottom of which contacts the top of the bracket 1, and the top of which is fixedly connected to the lower clamping plate 3. The guide assembly 5 includes a first fixing block 501 fixedly connected to the surface of the lower clamping plate 3. A rotating groove is formed on one side of the first fixing block 501. A second fixing block 502 is fixedly connected to the surface of the upper clamping plate 4. A groove is formed on one side of the second fixing block 502, and a circular groove is formed on the top of the second fixing block 502. A threaded sleeve 503 is rotatably connected to the inner wall of the rotating groove. A bolt 504 is threadedly connected to the inner wall of the threaded sleeve 503. The bolt 504 cooperates with the threaded sleeve 503. During the operation of the threaded sleeve 503... The upper clamping plate 4 is fixed to ensure that the upper clamping plate 4 and the lower clamping plate 3 can restrain the steel cable. The surface of the bolt 504 is fixedly sleeved with a fixing plate 505. The fixing plate 505 is fixedly sleeved on the surface of the bolt 504, and its bottom contacts the circular groove at the top of the second fixing block 502 to prevent the bolt 504 from moving axially during rotation. This ensures that the clamping structure between the upper clamping plate 4 and the lower clamping plate 3 is stable and reliable, and prevents the steel cable clamping failure due to the loosening of the bolt 504. The bottom of the fixing plate 505 contacts the inside of the circular groove. The inner walls of the lower clamping plate 3 and the upper clamping plate 4 are respectively rotatably connected with eight rotating wheels 6, which replace the sliding friction of the traditional rigid clamping plate, significantly reduce the wear of the steel cable surface, and extend the service life of the steel cable. The bottom of the bracket 1 is fixedly connected to the mounting block 7. The surface of the mounting block 7 is provided with fixing holes. The layout of the fixing holes of the mounting block 7 conforms to the general mechanical installation standard and can be adapted to the mounting base of various industrial equipment without additional modification, thus reducing installation costs and time. A placement seat 8 is fixedly connected to one side of the bracket 1. The surface of the placement seat 8 is provided with a placement groove. The placement groove adopts a U-shaped anti-slip design and its depth matches the diameter of the steel cable, which facilitates temporary storage and quick access. The surface of the placement seat 8 is fixedly connected with four limiting rods 9. The four limiting rods 9 are distributed in a rectangle around the placement groove to form a rigid limiting boundary to prevent the placed steel cable from tipping over. The inner wall of the cavity is provided with a rotating groove, and one end of the worm 202 is rotatably connected to the inside of the rotating groove. The cooperation between the rotating groove and the worm 202 forms a double-support structure, which greatly improves the stability of the worm 202 when it rotates, significantly reduces vibration and noise, and extends the service life of the component.
[0018] In this invention, the working steps of the device are as follows: First step: Motor 201 drives worm 202 to rotate at a constant speed. Worm 202, through a precision tooth design, meshes tightly with worm wheel 203 to achieve stable and backlash-free transmission. The rotational motion of worm wheel 203 is rigidly transmitted to connecting block 205 via high-strength rotating rod 204. Connecting block 205, as a transmission hub, accurately transmits power to the lower clamping plate 3 and upper clamping plate 4 fixed thereon. The two form a linkage rotation mechanism through the structure of worm wheel 203 and worm 202, which can achieve flexible angle adjustment of a large angle in the horizontal direction to meet the precise positioning requirements under different working conditions. The second step: By rotating the bolt 504 clockwise, its external thread and the internal thread of the threaded sleeve 503 form a helical transmission, and the bolt 504 moves steadily downward under the action of axial force. During this process, the upper clamping plate 4 and the lower clamping plate 3 move in opposite directions through a linkage structure, thereby constraining the steel cable and reducing the risk of derailment. At the same time, the fixing plate 505 is precisely embedded in the corresponding circular groove to form a mechanical limiting structure, which not only restricts the circumferential rotation of the bolt 504, but also effectively resists the risk of loosening under complex working conditions such as equipment vibration and stress through the rigid constraint of mechanical locking, ensuring that the clamping state remains stable and reliable during long-term high-load operation.
